It is such a challenge to explain GMT time vs. any individual member's time.
It was my understanding (maybe, hopefully, an incorrect misunderstanding) that this is not a likely option for the JamRoom Events Calendar.
Ning was never able to provide this for us, either.
But I'll give a high five YES! if this could be an option.
paul:
Add a 'location' select field to the user account form that translates to +/- hours then add/subtract that from event dates when displaying them?
No this needs to be done via Javascript. Something we can look into for a future release, but it won't be really quick.
